Application filed December 2, 1914. Serial No. 875,'lll3.

h all 'whom ymay concern lie it known that l, ALBERT l'lUnnnLL, a citizen of the United States, residing at lavenwood, in the county of Notlaway and State ot lllissonri, have invented certain new and useful ln'iprovements in St 'aw-Spreadl ers. of which the following is a specification,

reference being had to the accompanying drawings. i l This invention relates to certain improvements in straw spreaders and has relation Vbroadcast mechanism whereby the straw thrown over an increased area.

The invention also contemplates for an object the provision of a device of this general character havingnovel and improved means whereby any grain held by the straw to be distributed may he collected with convenience and facility.

lf`urtl'iermore, the invention has for an, oojcc' to provide a device of this general character having' novel. and improved means .vhereby the straw is automatically delivered to a teerlirngr mechanism and whereby such 'delivery ol the straw may be regulated with convenience.

The invention consists m the details of construction and in the combmatwn and arrangement ot the several parts of my im-A proved straw si'ireader whereby certain yimportant advantages are attained and the describe 'the same with reference to the'accom- 2 is a top plan view of the device as dis closed in Fig. l; Fig. 3 'is a sectional view taken substantially on the line 3 3 oi' Fig. 2; Fie'. l is a sectional view taken substantially on the line 4 'l of Fig'. l, with certain of the parts omitted; Fie" 5 is a rear elevarn tional View ot the device, as herein disclosed; Figi. a sectional view taken substantially on the line 6 6 of Fig. Fig. 7 is a 'tio-nal viewK taken substantially on the' line 7 7 of Fig. 2; Fig'. 8 is a fragmentary view, partly in side elevation and partly in section,

'illustrating the elevatingr mechanism, hereineinbodied, in detail; Fig. il is a view, partly inelevation and partly in section, illustratiinl' in detail the operative connection with the drive chain coactinp; 'with a rear supporting'A wheel; Fig. l() is a fragmentary view in cross section and on an enlarged scale of the delivery mechanism as herein embodied; Fig. ll is a fragmentary view, partly in elevation and partly in longitudinal section, of a, portion of the delivery mechanism asherein embodied; and Fig. l2 is a view in perspective, '(letaclietl, of a bearing' member herein embodied.`

As disclosed in the accom'ianying drawings, l denotes a. trame of predetermined d'in'iensions and preferably ot rectaninila' form having-disposed transversely of its rear yeXtrem/ity the axle 2 on the projected extrei'i'iitiesof which are. mounted the supporting wheels-3 while the forward portion ot' said traine is operatively supported by a steering: truck 4 of conventional construction and with which is 'adapted to coact any desired arrangement of draft rigging, lgenerally indicated `at 5. l

The longitudinal. ysides 6 of the` 'trame l are o'iE such a height as t0 a'l'l'ord a substarb tially box-like structure while the opposite extremities of such side' members are tied or connected by the sills 7. Disposed across the top of the 'frame l and directed longitudinally thereof are the spaced rods 8, the extremities whereof' beine' disposed through the sills 'Z' and engaged by the nuts or burs 8 whereby it will be readily perceived that"- the rods 8 are eli'cctively maintained in operative position.

The side members (i and the forward extremity of the frame l are provided with the eopings 9 to which are suitably secured the racks 10 of any desired construction and which are adapt/ed to ail'ord a basket or hop- Clt 'livery mechanism l). The opposite extremities of the side bars 1J( are provided with the depending racks l5 in mesh with the gears 1G suitably affixed to the shaft li' disposed transversely of the f'ame l adjacent its forward end and operatively supported by the side members (3 thereof. At a predetermined point intermediate its length, the shaft 17 is provided with a worm gear 18 in mesh with a worm 1S) produced on the verticatly disposed shaft 20 terminating in close proximity to the seat structure S and provided at its upper extremity with suitable means 2l whereby the shaft 20 may be rotated in either direction in order to adjust the positions of the side bars' l-t of the delivery mechanism D relative to the spaced rods 8, hereinbefore referred to.

At predetermined points intermediate their lengths the side bars 14 are tied or connected-by the cross beams 22 adapted to support an imperforate floor 23 over which is adapted to travel the endless chains 24: directed around suitable sprockets 25 fixed to the shaft ll and around the sprockets 2G fixed tothe transverse shaft 27 operatively supported by the side bars li adjacent their free extremities. At regular intervals' the chains .24 are connected by theI transverse slats 28 having projecting from |their outer faces the tines 68 adapted to pass between adjacent rodsv in order to conveyor deliver the straw: rearwardly of the-machine.

-It will now, it is thought, be-self-evident,

that the adjustment of the side bars 14 of the delivery mechanism D will determine 0r regulate the delivery of the. straw, for rea-l sons whichsare believed to beapparent. H

Adjacent. their rear extremities the side members 6 of the frame l are provided with the transversely disposed wall 29 having projecting therefrom at substantially midway its height, the horizontally disposed platform 30 through which are disposedthe vertical shafts 31, the lower extremities whereof being suitably supported in the bearings 32 on thel supplemental platforml 33 disposed below the platform 30, herein'` before referred to, and suitably connected' with the frame l, Each of the shafts 31 above the platform 30 has radiating there- "the machine.

from the arms 34 of predetermined length' and which are adapted upon rotation of the shaft ll to throw the straw broadcast.

llixed lo each of the shafts 3l at a poilu below the platform Chl is a beveled gear 35 in mesh with a similar gear Ilo mounted on an extremity of a stub shaft 3T ojwratively supported b v the platform ll, The stub shaft 3T has allixed thereto a sprocket 39 around which is disposed the sprocket chain .0 also directed around a sprocket '-ll fixed to the transverse shaft 4-2 operatively supported by the side walls ISS connecting:T the platforms l0 and 'll, and projecting therebeyond.

To each projected portion of the shaft 42 is atlixed a sprocket 43 around which is dis! posed a drive chain -H- also directed around an enlarged sprocket -L loosely mounted on the axle 2. hereinbefore referred to, and provided with a clutch member -hr adapted to coact with a second clutch member 4T carried by the adjacent wheel 215. The clutch members 46 and 1T are normally maintained in lockingr engagement through the medium 'of the expansible member 48, herein disclosed as a conventional coil spring' surrounding the axle 2 and interposed between the hub of the sprocket and a. stop L9 suitably positioned upon the axle.

1n view of the foregoing, it will be readily perceivedr that with the clutch members 46 and ldn locking engagement the shaft 3l will be caused to rotate upon the travel of In order, however, to maintain the shaft 31, o1' more particularly the sprockets 45, against rotation as desired, I provide in the hubs thereof the annular grooves 50 operatively engaged by the. forks 51, the extremities of such forks being operatively connected through the medium of the iexible members 52 with the opposite extremities of the lever 53 pivotally engaged at substantially its longitudinal center, as indicated at 54, with theiaxle 2 whereby it will be readily perceived that upon rocking movement being imparted to the lever in one direction, the clutch members 46 will be disengaged from the clutch members 47. Coacting with the flexible members 52 are the guide rollers 55 carried by the axle 2 and whereby the movement of the forks under the influence of the lever is materially facilitated.

Projecting laterallj7 from the lever 53 at its longitudinal center is an arm 56 having pivotally engaged with the extremity thereof the forwardly directed rod 57 also pivotally engaged with the lower extremity of the vertically disposed lever 5S terminatingin close proximity to the scat structure S and provided with a conventional spring latch 59 coacting with a rack (i0 whereby it will he readily perceived that thc occupant of the seat structure S may throw the 92 around which is disposed a. belt 93 also directed around a pulley 94 allixed to the projected extremity of the shaft 86. It is to be. observed that the pulley 94 is of materially greater diameter than the pulley 92, for reasons which are believed to be selfevident. I also lind it of particular'a'd vantage to dispose rearwardly of each of the shafts 31 the vertically disposed* and horizontally curved plate 95 which serves to assure a proper scattering of. the straw, as is believed to be self-evident.

From the foregoing description, it is thought to be obvious that an agricultural machine constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well `adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure )from the principles and spirit thereof and 'for this reason I do not Wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim: W
